I changed the primary connector and the family sort of works but maybe not 100%.

Hello,

In the previous versions, for elbows, the primary connector must point to the horizontal left and the secondary to the right upper quadrant.

This is the way I create all of my elbows, I am not sure if your elbow will work properly, but I never tried something different, maybe it works in newer versions.

Hi, I re-created the primary connector point to the horizontal left and the secondary to the right upper quadrant.

But doesn't know why also couldn't auto connect.. attached new file for reference. Thanks. (Revit 2020)

Hello,

I suggest you to check this family provided by Autodesk.

It has the necessary components to make it work properly.
